mtngoat - I'm surprised you refered to him as a "friend". Sounds like you split that friendship only because he is gay. Either way, I can't understand why you think the entire gay community is reading one personal homepage and somehow forming an opinion about you, a guy who lives 1,000 miles away from your "friend." But it's your prerogative.
Why don't you simply approach this as "I do not want you as a friend anymore because somehow you are now my sworn enemy since I cannot change my preconceived notions about your sexual orientation. I will never change and if I had a son or daughter who was born gay, I would kill it. Now take my name off your page or I will spend countless hours and dollars fighting to force you to take it off because I'm afraid that someone out of the 12 people in NJ who will look at your page will drive down to Dixieland and turn me into a flaming drag queen like I heard on the school playground when we were young."
I believe this is what is called standing up to the minority (FYI: non-gay-friendly people are the minority in 2001 - at least in the USA. Maybe you should try moving to another country.)
Oh, and if that doesn't work, try mentioning nicely that it's a violation of privacy and you don't want to have to take any sort of legal action that you two should just be able to handle yourselves.
